IMPROVEMENT IN CURTAIN-FIXTURES.

Specification forming part of Letters Patent No. 183,990, dated October31, 1876; application filed September 23, 1876.

To all whom it may concern:

Be it known that I, DAVID B. TIFFANY, of Xenia, in the county of Greeneand State of Ohio, have invented certain new and useful Improvements inCurtain-Fixtures; and I do hereby declare that the following is a full,clear, and exact description thereof, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

My invention relates to curtain-fixtures and it consists in a spikedpulley attached to the end of the curtain-roller, and endless chainpassing over said pulley, a catch, and a guide, all as hereinafter morefully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in whichFigure 1 is an end view of a curtain and roller with my inventionapplied therto. Fig. 2 shows the construction of the pulley.

A represents an ordinary grooved pulley, such as is commonly used on theend of acnrtain-roller. In the groove on this pulley are inserted orotherwise attached and permanently fastened a series of pointed pins orspikes, a at, extending radially at suitable distances apart. Over thispulley is passed an endless chain, B, made preferably of flat links tocatch upon the pins or spikes a of the pulley. By means of this chainthe curtainroller is easily rotated in either direction, so as to Windup or unwind the curtain, as desired and the curtain may be held at anyheight by simply hooking one of the links of the front part of the chainon a hook or pin, 0, fastened in the window frame. Below the pulley A-inthe window-frame is fastened a guide, D, through which the chain Bpasses, as shown in Fig. 1, so as to guide the chain properly to andfrom the pulley. The chain, at the bottom, is passed around a pulley, G,projecting from the window-frame.

I do not claim the roller of a window-shade having a pulley providedwith projections combined with an endless perforated strap, as I amaware that such is not new.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

The combination, with a curtain-roller and curtain, of the grooved andspiked pulley A, endless metallic chain B, guide D, hook U, and pulleyG, all constructed substantially as and for the purposes herein setforth.

In testimony that I claim the foregoing as my own I aflix my signaturein presence of two witnesses.

DAVID B. TIFFANY.
